nato is trying to keep this from escalating into a full war, but from the syrian perspective, this nato warning certainly puts the feeling that if there is a war between nato and turkey on one side, syria on the other, that the gloves would, indeed, come off. the latest video out of damascus shows some car bombs going off near a heavily-fortified syrian military compound. that points once again to foreign fighters, jihadist fighters coming in, primarily those trained in iraq and libya. and this really complicates things inside syria because no longer is it the rebels on one side wanting president assad gone and the government on the other side continuing to fight its own people. this group of extremists that has now come on means, jon, if in the future assad does decide to leave power, the civil war could easily continue between the rebels where local syrians want a better life for themselves and their country and the jihadists who clearly want an islamic state inside syria. jon, back to you. jon: leland vittert, thank you. jenna: flying dragon now on its way to international space stat
